SCRUBBING-MACHINE.

Specification of Letters Patent.

Patented May 20, 1913.

Application filed iDecembe r 2, 1911. Serial No. 663,536.

To all whom it may concern:

Be it known that I, FRANKLIN A. BRE'I'I, a citizen of the United States,residing at Oak Park, in the county of Cook and State of Illinois, haveinvented new and useful Improvements. in Scrubbing-h/Iachines, of.

' braces a device in which a quantity of liquid is sprayed upon thefloor, a scrubbing brush being operably ,mounted to scrub thefioor afterthe liquid has been sprayed thereon, after which a suitabledrying mopoperates over the floor to dry the surface thereof, the liquid tobe'sprayed upon the floor being retained ina reservoir, a secondreservoir being provided to receive the liquid after the same has beenapplied to the door with means for controlling the amount of liquid tobe sprayed upon the floor.

In the further disclosure of the invention, reference is to be had tothe accompanying drawings constituting a part of this specification andin which similar characters of reference denote corresponding parts inall the views, and in which Figure 1 is a side elevation. Fig. 2, is avertical sectional view taken on the line 2-2 in Fig. 4, looking in thedirection ofthe .arrow. Fig. 3 is a front, elevation, parts i the frame.

Referring more particularly to the views, I provide a carriagecomprising a frame 10, preferably consisting of an integral casting, therear portion of the frame being provided with an upwardly extendingplate 11 and having the sides thereof at the upper end of the frameformed into outwardly offset portions 12 to provide a seat 13. Formed onthe rear of the frame 10 are outwardly extending studs 14 having wheels15 journaled thereon and journaled on the front end of the frame 10 isan axle'lG having wheels 17 mounted to turn therewith.

- Mounted to repose upon the seat 13 of the frame 10 and dependingtherefrom is a waste reservoir 18, the upper end of the said reservoirbeing offset similarly to the portions 12 to provide a seat 19 on whichis mounted to repose a main reservoir 20, the bottom of the mainreservoir 20 being adapted to close the waste reservoir 18 as shown inFigs. 2 and 4, the main reservoir 20 being provided with a fillingopening 21 normally closed by a cap 22.

Keyed on the ends of theaxle 16, exteriorly of the frame 10, are toothedwheels 23, 24, the toothed wheels 23 being larger than the toothedwheels 24 and mounted to mesh with toothed wheels 25 keyed to the endsof an axle 26 journaled in the forward end of the frame 10 and havingmounted to rotate therewith a circular scrubbing brush 27, the latterbeing mounted so that the free ends of the bristles thereof will contactwith the surface of a floor 28. The toothed wheels 24 are mounted tomesh with toothed wheels 29 keyed to an axle 30 journaled in the frame10 and having mounted to turn therewith a drying mop 31, the latterbeing preferably circular in shape and mounted within the casing 10 asconveniently shown in Fig. 5.

Secured to the inner sides of the waste reservoir 18 are bearing members32 in which are mounted to slide horizontally,

studs 33 rigidly formed on the ends of a squeezing roller 34, mounted torotate with in the waste reservoir 18, an opening 35 being provided atthe front end of tlm reservoir 18 and through which the squeezing tionsof the casing 36 inwardly to form inwardly extending flanges 38. Theseinstruck portions surround said openings and form a plurality of raisedport-ions adapted to impinge against the mop, and also are beingprovided with shanks 4O encircled by expansible springs 41., the forwardends of these-id springs being adapted to abut against the bearingblocks 39 and the rear ends of the saidsprings being adapted to abutagainst blocks 42, having the free ends of the shanks 40 slidablymounted therein, the

mentioned blocks 42 being provided with otl'set circular shank portions43, constituting bolts adapted to receive nuts 44. To permit theaccommodation of the nuts on the bolts for securing the bearing members32 to the inner sides 0.1": the reservoir 18 and the nuts 44 of theblocks 42, the frame 10 is provided with vertically extending slots 45,the said slots being arranged immediately beneath the offset portions12, thus permitting the bearing members 32 to be'rigid-ly mounted on theinner sides of the reservoir 18 and also permitting the squeezing roller34 to be properly mounted within the reservoir 18. i i

A rearwardly extending inclined shelf 46 I is secured to the inner frontside of the reservoir 18, immediately beneath the squeezing roller 34for a purpose that will be hereswung upwardly, as will be readilyunderstood.

Mounted on the front end. of the frame 10 is a valve casing 54, havingconnection, by means of a pipe with the main reservoir 20, a circularapertured spraying tube being mounted to depend from the lower end ofthe casing 54 and arranged inunediately in front of the scrubbing brushV a valve-57 being connected to a hell cranh lever 58 by means of a link59, a suitable operating cord (50 being pivotaiiy connei" i, to an armof the be 1 crank lever 58 th. I l cord 50 being extended rearwai handle52, a suitable grip (it being: n i of the cord 60, adjacent In the use0'. Xl'ly( to scrub a floor flu in tilled with a fluid, sucl cleansingsolution and is then wheeled upon the floor, the operator being or asoapy stationed in the rear of the 1'; iage with his hands on the grip52, to user a i ward pressure on the grip and operate riuge over thefloor. how by puli'hg on the cord 61, the grip ti) will be c tedto openthe valve 57, thus permitting the tluid in the main reservoir 20 to Howoutwardly through the spraying tube 336, thus spra t i the fluid ontothe floor. Now as the car erated over the floor, the revoiuhle me e mentof the wheels 17 and the axie 1 5, wiii impart a rotating movement tothe scrubing the 'drying mop 31 by the action of the expansible springs41, will squeeze the dirty fluid and foreign matter out of the dryingmop, the mentioned fluid and foreign matter,

being adapted to flow into the squeezing roller 34, through the openings37 therein,

the dirty fluid and-foreign matter being then adapted to pass outwardlyfrom the squeezing roller and onto the shelf 46 from which the mentionedfluid will flow into the waste reservoir 18.

From the foregoing description it will b:; seen that when the carriageis operated over the floor, to be cleaned the floor is first subjectedto a spray of fluid and then scrublied, after which the surface of thefloor is dried by a mop and the foreign matter and dirty liquid,absorbed by the amp in its operation over the floor, is squeezed fromthe mop i received in the waste reservoir 18, ti leaving the floor in aclean and sanitary corn dition, it being understood that the operatorcan at all times control the amount of to be sprayed upon the floorwhile the pidityot' rotation of the scrubbing brush and the drying mop31 depends ent upon the rapidity with which the carria opt-ratedover thefloor.

in a device of the kind described the combin ation of a fluid receivingreservoir, a mop roller disposed exterioi'ly the' of, a roller disp dtr: twersely in said It -voir and m ng i'l'm'relrom partially, St 1roiler being r'med with a longitudinally spaced .and a shelf downwardlyinclined in sai fluid-receivin reservoir and havin its base ,in contactwith said second-named roller.

In testimony whereof I afhx my signature in presence of two witnesses.
